Product Description

Specifications:

Temperature range: 32-42°C
Environment temperature range: 12-38°C
Storage temperature range: -20-50°C
Measurement time: within 1 second
The scale choosing: °C or °F
Display mode: LCD
Memory function: 10 groups
Fever alarm, beeper function and low-battery display
Close method: shut-off automatically after 5 minutes ofnon-operating
An infrared (IR) thermometer contains an optical sensor,usually a thermopile, which can detect the infrared emissions fromany hot object

The magnitude and spectrum of infrared energy emitted dependson:

Internal temperature of the body
Temperature of the thermometer, which is also radiating IRenergy
Emissivity, which describes the efficiency of the surface forradiating electromagnetic radiation and is a dimensionless numberbetween 0 (smooth shiny surface) and 1 (dark rough surface)
Filtering effect of optical components, including the probecover

Description:

Infrared ear thermometers are designed to sense the temperatureof the tympanic membrane within the ear
The measured temperature is an average across the visualizedarea
The field of view may encompass adjacent ear structures,approximately 2°C colder than the tympanic membrane (typically37.3°C)
An instrumentation offset is usually applied which incorporatesinformation about the thermometer temperature and filtering effectof the optical components
Some devices also try to correct for the effect of averaging(making assumptions about the relative size of the tympanicmembrane in the field of view)
Forehead thermometers repeatedly sample the skin temperatureseeking peak values, caused by the presence of the temporal arterylying under the surface
Instrumentation offset values and physiological offset valuesare then applied to predict the temperature at another site,usually oral
All these devices use computational software to rapidly predictthe temperature
